The recent modifications of the French bioethics law, the therapeutic progress and the massive development of advanced genetic techniques (such Next-Generation Sequencing (NGS)) with a rapid decrease in costs imply to question the extension of Newborn Screening (NBS) to new actionable pathologies and the acceptable and relevant methods for its possible expansion. International studies are beginning to determine the potential place of NGS in NBS. In this perspective, the SeDeN project aims to fully assess the social acceptability of these issues by measuring the diversity and consistency of expectations of French health professionals, parents and public policy makers.

The SeDeN-p3 Study focuses on the opinions of parents. It aims to analyze the perception of parents in different situations: birth, early childhood, child screened in the framework of the national neonatal screening program, etc. The objective of this part is to study the understanding and expectations of parents in France regarding the extension of newborn screening as well as their preferences regarding its conditions (information, types of pathologies, screening methods, etc.).
